To all whom it may concern.-

Be it known that I, EJNAR FABRICIUS- B-JERRE, citizen of the Kingdom ofDenmark, and residing at Frederiksberg, near Copenhagen, Denmark, haveinvented certain new and useful Improvements in Absorbent Pads, of whichthe following is a specification.

This invention relates to the of a liquid-absorbing gauzelike from aknown fibrous or cellular material, say cellulose wadding, peat fibres,felt, waste sponges, or the like which is covered on one or both sidesby crossing threads forming a gauze-like surface and entering into aninseparable connection with the fibrous material so that the lattercannot during its use be decomposed by soaking or otherwise.

The fibrous material may be treated in av known manner in differentways, that is Iproduction -it may be sterilized, freed from grease inorder to increase its absorbing ability, or weakened by mechanical or.chemicaltreat- The material must be such be mechanically manufactured,that is, the fibrous or cellular mass is at first in the way known fromthe manufacture of paper or by spinning machines formed into an endlessbelt of a suitable width and thickness, and, thereafter,-rolled orfolded together so as to give the ready material its proper shape andthickness. Further the material is sewed by crossing threads in aspecial machine so as to produce the above mentioned gauze-likecovering, and subsequently cut or stamped out to obtain a shapecorresponding to the purpose in question. Finally it is provided withsewed or bound straps, bands or the like in order to enable it to besecured, and it is then ready for use.

The above mentioned various mechanical treatments of the material may becarried out in one single machine, or the material may pass severalmachines each performing one of said treatments. v

The invention is clearly illustrated in the accompanying drawing, inwhich Fig. 1 is a top plan view of a portion of the material,

Fig. 2 is the bottom plan view thereof,

Fig. 3 is a transverse section through the material, and

brous pad separately y the stitching is made in such a that it may Fig.4 is a transverse section through a modified form of the inventionemploying twolayers of the material one of which is water-proof.

Referring now, more particularly, to the accompanying drawing there isprovided-a pad a of fibrous material through which threads I) are drawnso as to form on the engaging surfaces a auze-like covering inconnectewith the material.

Preferab manner that rows of chain stitches are laid in one directionand loose threads are arranged below and engaged b said stitches on theengaging surfaces 0 the material and preferably intersecting said chainstitches at right angles so as to form substantial squares as indicatedin the drawlngs.

In Fig. 4 there isshown a slightly modified arrangement com risingsuperposed. layers a and a", the ayers being of an absorbent naturewhile the layer a is impre nated in a'known manner so as to be ren eredwater-proof, the purpose being to prevent the liquld absorbed by thelayer a from penetrating through the layer .a". The threads 6' arearranged in the same manner as described in connection with Figs. 1 and2 being of course passed through both of said layers so as to hold themtogether. The ads, as intimated, are provided with a binding or band 0along the marginal edges so as to prevent the material from fraying atsaid edges.

The fibrous material treated 'as above is intended for use in the sicknursing as dressing, operating serviettes, catamenial sacks,childsnapkins', breast napkins for nursing ladies, towels,handkerchiefs, and in the general in all cases where a great absorbingability is important.

After the use the gauze-like fibrous material is discarded which is aninvaluable advantage in hygienic respect. As the fibrous material may bedelivered in a sterile state, it will be preferred in many cases toother materials used hitherto.

A special employment of the materialis for childs napkins. Experiencehas shown that a childs napkin, of this gauz'e-like fibrous materialhaving a lesser weight than a napkin of the best suited materialshitherto known is as ood as two such napkins.

Having thus 11y described the inveneluding a pad-like bod tion what isclaimed as new and desired to thickness, and a gauze-like covering ofcross threads arranged on one side only of the pad-like body withthreads of the coverin entering intoan inseparable connection wlth thepad-1ike.body.

2. A pad of the character described formed of a layer of an absorbentfibrous material of suitable shape and thickness, a waterproof layer offibrous material arranged adj aoent one surface of the absorbent threadsarranged on one face only of the absorbent layer with threads'of thecovering entering into an inseparable connection with the layers so asto hold them together.

substantially as and for the purposes set forth.

3. A device as claimed in claim 1, wherein bindings are secured tocertain edges of the pad-like body to prevent unraveling and frayin ofthe material at said edges, substantia ly as and for the purposes setforth.

In testimony whereof I afiix my signature.
